Abstract
A battery housing with an integral latch and a cantilevered spring finger positive displacement mechanism is disclosed. The slide-on battery is captivated by guide rails on each side of the mating surface of the battery housing. When the battery is properly located, a torsion bar latch locks the battery in place. When the latch is activated by the user to remove the battery, cantilevered spring fingers force the battery housing away from its locked position.
Claims16
A slide-on battery housing for a portable radiotelephone, enclosing electrochemical cells and having at least one surface by which the battery housing assembly is attached to the portable radiotelephone, the battery housing comprising:
- a latch mechanism attached to the battery housing for locking the battery housing to the portable radiotelephone;
- at least one positive displacement spring finger mechanism disposed on the attaching surface of the battery housing and cantilevered in a direction perpendicular to the plane of the attaching surface;
- and
- at least two guide rails on the attaching surface of the battery housing for securing the battery housing to the portable radiotelephone further comprising:
- (a) lip portions perpendicular to the plane of the attaching surface and on opposing edges of the attaching surface extending at least part of the length of said opposing edges and
- (b) at least one elongated protrusion on facing surfaces of each said lip portion and extending along each said lip portion parallel to the plane of the attaching surface.
A battery housing for a portable radiotelephone having at least two mating housing portions securing electrochemical cells therebetween and having at least one surface by which the battery housing may be detachably connected to the portable radiotelephone further comprising:
- (a) an elongate beam element supported at each end to form a torsion bar,
- (b) a push button lever element disposed perpendicularly to the center line of said torsion bar and between the two ends of said torsion bar, and
- (c) a catch element lever disposed perpendicularly to the centerline of said torsion bar and between the ends of said torsion bar;
- at least one positive displacement spring finger mechanism disposed on the connecting surface of the battery housing;
- and
- at least two guide rails on the connecting surface of the battery housing for securing the battery housing to the portable radiotelephone.
A battery housing for a portable transceiver, enclosing electrochemical cells and having at least one surface by which the battery housing assembly is attached to the portable transceiver, the battery housing comprising:
- a latch mechanism attached to the battery housing for locking the battery housing to the portable transceiver;
- a positive displacement mechanism disposed on the attaching surface of the battery housing;
- and
- at least two guide rails on the attaching surface of the battery housing for slideably securing the battery housing to the portable transceiver.
